Instructional Ideas
- In the opening exercise, ask class members to create their own triangle before constructing the midsegment; comparisons can then be made between the unique triangles and relationships discovered
Classroom Considerations
- Construction tools are required for individuals
- Learners should be familiar with a midpoint construction and how to use a protractor
Pros
- Hands-on approach motivates learners to discern patterns
- Provides instructional guidance and reasonable progression of examples
Cons
- None
